Methodology: 1) Controlled randomised intervention study (3 years). Subjects: persons older than 65 in health district 7 of Madrid with acute (< 3 months) DIMS. Intervention group patients will be attended by rheumatologists acording with clinical (diagnostic and therapeutical) protocols. Control group will receive the routine attention from the Health System. Efficacy and costs variables will be collected through monthly structured telephone interviews performed by independent personnel blinded to the intervention group. Efficacy will be measured by differences between groups regarding: 1) time to improvement in the baseline DIMS episode, 2) number of subsequent DIMS, and 3) total number of DIMS days. An economic evaluation will be performed from a societal perspective.
